Characteristics of colorectal cancer in young patients at an urban county hospital.
Colorectal cancer (CRC) is a disease primarily affecting an older population. The incidence of CRC in young patients has been rising. The purpose of this study was to evaluate the characteristics of CRC in an ethnically diverse, young population. Two groups of patients with CRC (40 years old or younger and 60 years old or older) treated from 1998 to 2005 were retrospectively evaluated. Forty-one young patients with CRC were identified. Hispanics constituted 51 per cent of the young population. Forty-four per cent of the lesions were right-sided in the young group compared with 21 per cent in the older group (P = 0.004). Advanced tumor stage (T3 and T4) was noted in 87.8 per cent of the young and 63 per cent of the older patients (P = 0.002; OR, 4.08). Poorly differentiated tumor grade was more common in young patients (P = 0.003) as well as mucinous/ signet ring characteristics (P = 0.005). Young patients had an increased likelihood of a family history (P = 0.0001). Operative intervention and survival were similar for the two groups. Our study confirms, in an ethnically diverse young population, that CRC tends to be advanced stage, aggressive, and frequently nonoperable at the time of diagnosis. It is important for physicians to recognize the poor outcome of CRC in a younger population and consider an aggressive approach to diagnosis and early treatment.
